The product detection switch 21, which is the gist of the present invention, includes a sold lever base member 210 and a sold lever base member that rotate from the respective holes 2B provided in the rear wall 2A to the inside of the product storage shelf 2. Each hole formed in the sold out lever base member 210 is rotatably supported by the micro switch 212 and the switch base member 211, which are the product detection units fixed to the switch base member 211 installed in the 210, It is comprised by the sold out lever 214 which rotates inside the goods storage shelf 2 from 213. As shown in FIG.

The sold out lever base member 210 is axially supported on the rear wall 2A as the shaft 215 and protrudes inside the product storage shelf 2 as a spring 216 which is a means for applying a first force. Strength is applied.

In addition, the lower end of the circular guide portion 217 and the restriction to contact the rear of the rear wall 2A at the time of maximum rotation of the sold out lever base member 210 formed outward from each hole (2B) to regulate the rotation The surface 218 is provided, and each hole 213 which makes the sold out lever 214 rotatable is formed in the intermediate part.

The force is exerted so as to protrude from the inside of the goods storage shelf 2 by the return force.

In addition, the lower end portion is provided at the arc-shaped guide portion 221 and the rear end of the guide portion 221, and is formed in the width direction and formed longer than the width of each hole 213, so that the maximum rotation time of the sold lever 214 is achieved. A regulating shaft 222 is provided in contact with the rear surface of the sold lever base member 210 to regulate rotation.

In addition, the spring 216 of the sold lever base member 210 is set to be stronger than the return force of the button portion 220 of the micro switch 212.

Next, the operation of the product sold out detection device of the vending machine of the present invention will be described.

First, the case where the long goods G near the length (depth) of the front-back direction of the goods storage shelf 2 is stored is demonstrated.

When the stored goods G are compressed against the sold lever 214, the sold lever 214 rotates backward while pushing the button portion 220.

After the article G is rotated behind the main lever 214 and the article G contacts the sold out lever base member 210, the sold lever base member 210 is moved against the force applied by the spring 216. (The product G that is received by sliding downwards from the top contacts the sold out lever base member 210 first, so that the sold out lever base member 210 is rotated backwards and then touched the sold out lever 214. The product G is detected by rotating the sold out lever 214 backwards. This state is shown in FIG. When the last product G before the product is sold out, as shown in FIG. 3, the product G does not come into contact with the sold out lever 214 and the sold out lever base member 210, so that the sold out lever 214 and Sold out lever base member 210 is rotated to protrude into the product storage (2).

The guide part 217 of the protruding sold lever base member 210 is located on the upper surface of the goods G, and the goods G mounted on the top of the extruded plate 32 return to the standby position of the extruded plate 32. When the product G is inclined to the front surface and becomes unstable, and when it is going to fall from the discharging opening 26, the upper surface of the product G abuts, so that the front slope can be suppressed, and misfeeding can be prevented.

The next time the short product is stored, the sold out lever 214 protrudes forward as long as the stroke (a) of the sold out lever 214 has satisfied the stroke (b) of the sold out lever base member 210. The product which is as short as the stroke b of the base member 210 can be detected by the sold out lever 214.

Therefore, the stored short product rotates the sold out lever 214 to detect the product (the product received by sliding from the top to the bottom is first brought into contact with the sold out lever base member 210 so that The product is detected by being guided forward by the applied force, sliding, and touching the sold out lever 214 to rotate the sold out lever 214 backward. This state is shown in FIG.

Since the force applied by the spring 215 side of the sold lever base member 210 is stronger than the force applied by the button portion 220 which applies the force to the sold lever 214, the product which abuts against the sold lever 214 There is no rotation of the sold out lever base member 210 before the rotation of the sold out lever 214 ends.

As described above, even if the depth dimension of the product is changed by at least the stroke of the sold lever base member 210, the presence or absence of the product can be reliably transmitted to the micro switch 212.

In addition, in this embodiment, the product detection switch 23 is installed on the rear wall 2A, and the change in the depth of the product is coped. However, the product detection switch 21 is installed on the side wall to change the width of the product. May correspond to.

Even if the size of the product to be stored is changed according to the present invention, since the product can be reliably detected without changing the setting of the sold out detection means, the trouble of changing the sold out detection means when the type of the product to be stored is changed can be omitted. There is a number.
